Bolts for shifting cylinders

Bolts for shifting cylinders are the essential element in the design of the mechanism of S-valve shifting. They transmit the drive from the cylinders to the swing lever. The shifting cylinders are connected to the swing levers by means of bolts and they drive the S-valve in the reciprocating movement. Depending on the model of concrete pump the bolts can include in it’s design the lubricating system. Normally the bolts for shifting cylinders work in pair with bearing bushings that are positioned in the swing levers and S-valve housings.

The basic bolts for shifting cylinders which are used in the concrete pumps:
